Course Overview:

DTI prepares students to work as private investigators or in other similar occupations. We offer instruction through home-study via a combination of printed manuals and online training. There is no classroom training. Instruction consists of 35 printed lessons with multiple training components, videos, tapes, and field exercises with seven open-book multiple choice examinations. Upon successful completion of the course, we will issue the student a DTI diploma that documents his or her mastery of key investigator skills and professional knowledge. The average time to complete the course is three to six months, but students have up to 24 months to complete the program. For more information, click on the following topic links:
